在河南生态条件下，研究了系统化学调控对硬粒小麦生长发育的影响。结果表明，系统化调技术能明显提高硬粒小麦冬前次生根数目、叶面积系数，增强植株抗逆性；降低硬粒小麦株高，改变茎秆结构，增强植株抗倒性；增强植株生育后期叶片功能，延缓衰老，提高光合强度
In Henan ecological conditions, the effects of systemic chemical regulation on the growth and development of durum wheat were studied. The results showed that the system of tune transfer technology can significantly increase the number of secondary roots and leaf area coefficient of winter wheat before winter, enhance the plant resistance; reduce the height of durum wheat, change the stem structure, enhance the plant lodging resistance; enhance the plant growth Late leaf function, anti-aging, improve photosynthetic intensity
